IMPROVEMENT IN LASTlNG-MACHINES.

Specification forming part of Letters Patent No. 209,232, dated October22, 1878; application filed March 1, 1878.

To all whom it may concern.-

Be it known that we, lrEORGE W. COPE- LAND, of Malden, in the county ofMiddlesex, in the Commonwealth of Massachusetts, and JOSEPH E. CRISP, ofBoston, in the said Commonwealth have invented an Improvement inLasting-ll/Iachines, of which the following is a specification:

This invention consists in a machine for lasting the uppers of boots orshoes, having two or more gouge-shaped knives arranged to automaticallygouge or out V-shaped sections or scallops from the edge of an upper, inconnection with folding-plates adapted to be closed upon the insole infolding the edge of the upper during the operation of lasting,hereinafter more fully described.

In the drawing, Figure 1 represents our invention.

In lasting the upper by machinery which operates to fold its margin uponthe insole, fitted upon a last, considerable difficulty is experiencedfrom the fact that upon some portions of the bottom of a last,particularly at the toe and heel, the upper has had to be folded over orcrimped upon itself by the action of the folding-plates, necessitating avery nice adjustment of the lasting mechanism. At the toe and heel theamount of upper which has to be removed is increased, from the fact thatthe counter is folded or turned upon the insole with the upper. It isalso necessary, before applying an outsole to the insole, to skive ofi',dress, or trim the unequal portion from the folded edge of the upper andcounter, in order that the surface upon which the outsole is fittedshall be as level aspossible. If, however, V-shaped sections or scallopsare removed from the edge of an upper, thereby depriving it of itsfullness, the lastingplates can be closed much more easily and withoutliability of damage to the upper or to the plates with theherein-described mechanism for removing the same during the lastingprocess.

In an application which we are about to make we shall claim thepreparation of the upper by cutting V-shaped scallops therein at certainintervals along the edge thereof before the same is lasted.

Our device consists in the gouge-shaped knives A, supported upon thejaws B, and pivoted at]; to the carriages C, which are provided with aclosing and opening movement by means of the rack c, gearing D, and thehandle d.

By pivoting the frame or jaw carrying the knives in the manner shown, avertical adjustment in relation to the insole is provided by means of aset-screw, e, that bears upon the arm or lever which carries afriction-roll at its end, to give the knife-blade increased verticalautomatic adjustability by the contact of said roll with the plate 9.

In operation it is intended that the V-shaped knives shall advanceduring the folding of the upper upon the insole and remove V-shapedsections from the edge of the upper.

The advantages of this invention consist in the means described forautomatically removing such portions of the edge of the upper as may benecessary either to lessen the strain upon the lasting-plates, or toprepare the upper for the reception of the ontsole or for both.

\Ve claim and desire to Patent In a machine for lasting the uppers ofboots and shoes, the combination of two or more gouge-shaped knives,arranged to automatically gouge or cut V-shaped sections or seallopsfrom the edge of an upper, with foldingplates adapted to be closed uponthe insole in folding the edge of the upper during the operation oflasting, substantially as specified.
